According to astronomers, gold on earth is the result of cataclysm collision of exotic stars. Astronomers reported on Wednesday that most of the lighter elements were created by dying stars billions of years ago in the universe.

The oxygen and calcium found in bones are among the examples of lighter elements created by the dying stars. However, astronomers said that it can be true for some of the heaviest forms like gold.

A Harvard astronomer Edo Berger led a team to conduct a study. They found that the collision of two neutron stars is more likely to have created gold. Neuron starts are those stars that are already collapsed and have remains of imploded stars.

These are incredibly dense objects and weigh 1.4 times as much as the sun. Berger said about once every century in our galaxy the ordinary stars explode. But collisions of two neutron stars happen about once in every 10,000 years. He said that it seems that heavy elements were created after a week of their collision.

Berger said, "Call it the golden glow. In this case, we were able to observe it for the first time and see how the merger seems to be producing the heavy elements".
